Abstract
An electric steering lock device of the invention includes: a rotating body (worm wheel) that is driven by a motor to rotate in an unlocking direction and a locking direction; a first cam section and a second cam section provided in the worm wheel; a lock member that follows the first cam section to be displaced between a lock position and an unlock position; and a lever member that follows the second cam section and that is positioned, when the lock member is positioned at the unlock position, at a waiting position at which the lock member is allowed to move, and that is positioned, when the lock member is moved to the lock position, at a retention position at which the lock member is blocked from moving to the unlock position.
Claims7
An electric steering lock device, comprising:
- a rotating body that is driven by a driving source to rotate in an unlocking direction and a locking direction;
- a first cam section and a second cam section provided in the rotating body;
- a lock member that follows the first cam section to be displaced in a direction orthogonal to a rotation axis of the first cam section between a lock position at which the rotation of a steering shaft is blocked and an unlock position at which the rotation of the steering shaft is allowed;
- a housing and a cover that form a part accommodation room for accommodating the rotating body, the first cam section, the second cam section, and the lock member;
- and
- a lever member that slides, while following the second cam section, so as to be able to be engaged with or disengaged from the lock member,
- wherein:
- the lever member is structured to:
- be positioned, when the lock member is positioned at the unlock position, at a waiting position at which the lock member is allowed to move, and
- be positioned, when the lock member is positioned at the lock position, at a retention position at which the lock member is blocked from being moved to the unlock position.

- wherein:
- the lever member is structured to:
- be positioned, when the lock member is positioned at the unlock position or the lock position, at a retention position at which the lock member is blocked from being moved to the unlock position, and
- be positioned, when the lock member is located between the unlock position and the lock position, at a waiting position at which the lock member is allowed to move.
